8/16/13 Hungry Hollow North Pit

Recommended Posts

lmacfadden

I went to the North Pit of Hungry Hollow for a few hours on Friday. I spent most of my time digging through the clay piles and walking around the water's edge, scoping out a few recognizable shapes that are by now completely camouflaged by the clay. It's amazing that my eyes even zeroed in on my tiny trilobites but I guess they had waited long enough for me to take them home, and today was the day! One trilobite turned out to be just the head but the other is pretty cute.

I met one hiker from Pennsylvania (Greg) that came through the trail along the North side of the river. I introduced myself and we chatted for a few minutes. i always enjoy meeting tourists from different parts of the country.

As I headed out, I decided to try the north cliff near the parking area and there I found a very nice Heteroschisma alatum (blastoid). It is about 1/4" wide and 3/8" long. In my pill bottle it went! I hope the photo is clear enough to see the detail.

I got called back home or I would have stayed there a few more hours, even though the sun was beating down on me. Even one good find keeps me there longer than I anticipated!

Incidentally, I went home with a large bag of garbage that I collected in the pit. I try to take anything out (cans, bottles, plastic bags etc) that I can, each time I go there and it always surprises me that I find more the next time I go. I hope people will be mindful that it's a privilege for us to be able to dig there at the generosity of the land owners. Please take your litter home with you.

Another decent mini-trip Lise. Your blastoid is likely H. canadensis, not H.alatum. Will there be anything left for me next time I get down there????? ;)

Thanks Kevin. I researched it as best I could. The detailed lines seemed to match up to H. alatum but it is on the grey side as opposed to the yellow/brown. I appreciate the more accurate ID!

When are you coming down? I'll be sure to leave something there for you! :P

Kevin - can you take another look? You can see H. alatum here http://strata.geology.wisc.edu/mibasin/showfull.php?id=141) my find is on the left, and H. canadensis (from google images) on the right.

Except for color, don't you think my find has more of the details of H. alatum?

I see stronger similarities in the right one.

Thanks Auspex - maybe I'm comparing the wrong details. I was particularly looking at the "stripes" (circled) on the blastoid as I did not see that detail on H. canadensis.

Excellent finds. I really like the blastoid. What is the fossil in the top left of the first pic?

Thanks Pete. In the top left is a tiny spirifer (brachiopod). Possibly Spirifer thedfordensis.

Thanks crinus! I concede. Heteroschisma canadensis it is!

Actually I believe that canadense is the correct one. I know some use canadensis but that would be wrong. You also have to be careful with arkonense and arkonensis. I have been know to use both but only one is correct.
